Title: Prodn. of cellulose pulp - from wood based raw material by digestion with catalysed ammonia at low concn.
Inventor: THILLAIMUTHU JEYARETNAM
IPC: D21C7/00
Filed: 1975-07-28
Abstract: Cellulose pulp may be prepd. from woody raw materials by cooking at elevated temp. and pressure in the pressure of aq. NH3 and a catalyst. The process is improved by using an NH3 conc. of ca. 1 wt.% in the presence of 0.25-0.01 parts of the hydrazine hydrate per pt. of NH3. The digester used for the cooking process remains filled to an extent such taht the free space above the batch is not >5% of the total digester volume. Advantageously, for soft woods, e.g. pine the hydrazine hydrate used represents 0.1 part of the ammonia present. The use of a more dilute NH3 enables wood-based raw materials to be treated in the same time and at the usual pressure as for e.g. bagasse, straw, bamboo etc.

Title: Simple tuner for radio receiver - has nonlinear potentiometer applying nonlinear tuning volts to make varactor diode linear
Inventor: JACKSON CHARLES LEON
IPC: H04B1/08
Filed: 1975-08-22
Abstract: The simple tuner, for radio receivers, consists of a potentiometer coupled by its slider to the varactor tuning diode and by its main terminals to a constant bias voltage. The potentiometer's resistance element is non-linear such that the varactor diode's non-linear voltage/capacitance properties are compensated. That is: a linear movement of the control knob that drives the slider results in a non-6inear biasing voltage and a linear change in tuning capacitance. The potentiometer's slider consists of a sprung wiper moved by the control knob over a curved non-linear resistance path.

Title: Tractor gearbox synchronising clutch - has multiple inclined friction discs each side of internally and externally toothed collar
Inventor: DROESCHEL HELMUT
IPC: F16D23/06
Filed: 1975-09-01
Abstract: A tractor gearbox includes a gear coupling with an operating collar (22) which is normally held in a neutral position by radially spring loaded pins (27, 28, 29). The collar (22) has internal gear teeth (23) which, after coupling, are in mesh with either one of the neighbouring gear wheels(1, 2). Before the gears are coupled, a synchronising plate clutch (12, 19) produces equal rotational speed between the gear wheels. A number of friction discs (20) are located in an annular chamber which is formed by two tapered friction rings (13, 14). When the collar (22) is operated, the axial force moves the friction discs (20) into a true radial plane, thus producing a lever action which increases the operating force. The synchronising clutch is thus operated so that the selected gear can be engaged.
